The NC feeder is a versatile feeding mechanism that offers compatibility with a wide range of punches and processing machines, including shearing machines, hydraulic presses, forming machines, and laser cutting machines. In this article, we will explore the different control methods associated with using the NC feeder with punches and other types of processing equipment, as well as discuss an effective solution for achieving continuous and automated stamping production during long-step feeding operations.

Control Methods for NC Feeder with Punches and Processing Machines

  1. NC Feeder Control with Punches

When the NC feeder is utilized with punches, its operation primarily relies on the punch cam signal for control. The punch cam signal dictates the movement and feeding of the NC feeder in coordination with the punch machine, ensuring precise and synchronized actions between the two components.

  1. NC Feeder Control with Other Processing Machines

Contrary to its usage with punches, the majority of cases involving the NC feeder and other processing machines require the feeder to send a cutting signal to control the operation of the equipment. This cutting signal serves as a command that directs the processing machine to initiate the necessary actions for cutting, forming, or any other relevant processes.

  1. External Cutting Signal Control

In specific situations where certain customers demand it, the NC feeder can also be employed to control the punch operation through an external cutting signal. This control method is commonly employed in long-step feeding operations within punch machines.

Challenges in Long-Step Feeding with NC Feeder and Punch Machines

When the NC feeder is combined with a punch machine for long-step feeding, the feeding time of the feeder tends to be relatively long. Adopting the standardized punch control method designed for continuous stamping feeding may lead to an issue where the punch slide reaches the bottom dead center position before the NC feeder completes the feeding process. Consequently, this misalignment hinders accurate feeding operations, hampering production efficiency.

The Solution: Utilizing NC Feeder’s Cutting Function for Automated Stamping

To overcome the challenges associated with long-step feeding, a more efficient and reliable solution involves leveraging the cutting function of the NC feeder to control the punch machine’s operation. By implementing this solution, continuous and automated stamping production during long-step feeding can be achieved.

In practical use, an additional cutting control line is connected from the NC feeder’s electrical control box to the foot switch of the punch machine. When the punch machine is switched to the foot switch mode and the NC feeder’s automatic feeding is initiated, the NC feeder sends a cutting signal to control the punch machine for automatic stamping operations. This integration ensures stable and automated stamping production during long-step feeding, significantly enhancing overall productivity.

The NC feeder, renowned for its versatility, offers compatibility not only with punches but also with various types of processing machines. Depending on the equipment used, the control methods for the NC feeder may vary. However, when it comes to long-step feeding operations, integrating the NC feeder’s cutting function with the punch machine provides an effective solution for achieving efficient and automated stamping production. By adopting this approach, manufacturers can enhance productivity, streamline processes, and meet the demands of continuous stamping with precision and reliability.
